Cook rice noodles according to package instructions. Most brands of rice noodles only require the rice noodles be placed in boiling water for 5 minutes and stirred a couple times. Drain the pasta and rinse with cold water.
While the rice noodles cook, pour the Tamari sauce, rice vinegar, peanut butter, olive oil, Sriracha sauce, cane sugar, ginger and garlic into a small blender or food processor to make the dressing.
Transfer the cooked noodles to a large bowl. Then add the spiralized carrots, red peppers and cilantro to the cooked noodles.
Pour the dressing over the rice noodles and vegetables, and toss to combine.
Serve with roasted peanuts, chopped green onions, fresh cilantro and lime wedges, if desired.
